IMPROVEMENT IN MACHINE FORDRAWING AND SPINNING Woot., atc., lFROM THE tcARDING-MACHINE. y

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom tt may concern:

Be it known that I, JOHN GOULDING, o Worcester, in the county of'Worcester, and State of Massachusetts, have invented certainImprovements in Oarding and Spinning; 'and I do hereby declare that thefollowing, taken in connectionivith 4the Adrawings which accompany' andform part of this speciiication, is a description of my invention,suiiicient to enable vthose skilled in the art to practise it.

These improvements relate particularly to a method of spinning yarndirectly from the carding-cylinder, so as to obviate the necessity ofemployment of a mule, or other separate machine, to operate upon thesliver made by the carding-machne; and

The invention consists, primarily, in the combination, with theeenling-mechanism, and the draw-oli" rolls and twister-tubes, ofalstopping-deviceor brake, which, falling upon thel sliver, (after itsdelivery from the card-cylinder, through the draw-rolls and through thefirst twistertub`e,) pinches it against a bar, and prevents the backsliver froni further delivery, until the front draw-rolls have drawn thefront part of the sliver, (between them and the bar,) after a secondtwist has been producedbyan.additional twister-tube, thus producing ayarn. having a uniform and even twist, 'the yarn passing from the seconddraw-rolls to the main twister-dier, and thence to thebobbin.-

rlhe invention alsofcpnsists in the mechanism for producing the rise andfall of the bobbius, and graduating the rise and fall, so as to properlytill the boby bins from head toy point.

The drawings represent a machine embodying these improvements.

Figure l shows the machine in side elevation.

Figure 2 is a vertical longitudinal section of the machine.

a d'enotes the frame, mounted in suitable bearings, at the top -of whichis the main card-cylinder b, to the action ot' which the sliver issubjected, after leaving the second card', the sliver entering themachine between the top roll c and feed-rolls d tl, thence passing underthe leader, or roll e, over the tumbler f, from which it is taken, bythe main card-cylinder b, around, and acting with which, are theclearers g g, workers h. h, fancy It, and doer k, from which dotfer thecarded sliver or roving is stripped, oi' -wiped 'by the wiper ortake-od' roll l.

The card-clothing is not shown in the drawings, the airangementandoperationof the carding-mechanism being the' same, or much the same, asin other' carding-engines.

From the take-olf roll, the roving passes to and through a twister-tube,m, to and between drawingtube, p, to draw-rolls q q, which rotate at anincreased velocity, the roving being drawn out or attenuated .by

these rolls, under the temporary twistimparted by the twister-tube p.

Instead, however, of passing the roving directly to the twister-tube pand dra\v-rolls q q, a brake or holdfast mechanisin is employed, asfollows, to' intercept the delivery ofthe roving, amlallow it to bestretched while twisting. p o

Across the frame extends a stationary baur, in the top of which is alonggroove, s. Into this groove drops the tooth j,`ot` a jaw, t, and whenthe roving is passing under this tooth or gripe, it' the tooth descends,it gripes the roving and arrests its travel, so that the roving, fromthe gripe to the front draw-rolls, is stretched or attenuated, the twistand stretch extending into the large as well as into the small parts ofthe roving, and reducing it all to a uniform size, after which thegriper is raised, the roving is again drawn along, (its slack beingtaken up,) until another rotation of the rear draw-rolls, whenthe'gripcr againdescends and nips the roving, and so on, thus impartiiiga uniform stretch and a uniform size to the roving, and bringing it intocondition for the final and permanent twist 'preparatory to 'its bei ngwound upon the'bobbin.

"lhe griper is worked as follows:

The griper-jaw is attached to acollar, lu, fixed upon a1ocker-shat,-r,on the end`- of which is an arm, w, resting upon 'a cam, at, on theslm-ft of the adjacent draw-roll n, and at each rotation of the roll n,the cam lifts the arm w, and therebyraises the gripe or tooth j, andreleases the roving, while, as thc campoint passes around, the arm isreleased, and the gripe or tooth falls yand rests by its weight/(and theweight of the'arm w) upon the roving, holding it while'the roving nadvance is stretched while being twisted. Thus stretched and madeuniform, or nearly uniforln in size, the roving is ready fdr itsnal' orpermanent twisting by the tlier, ythat lays the yarn, thus spun andtwisted, upon the bobbin.

The rotative movements off'the feed-rolls, main card, clearer, worker,Ste., and of the draw-rolls, the twisters, and the iiiers', are effected.by geared and belted connections with the main shaft, as seen in thedrawing, or in any other suitable manner.

The iiiers are-journalled in stationary rails, ai,'"a'nd hang below thelower rail, as seen at iig. 2. The bobbins stand upon spindles, b",mounted in a rising andv falling frame c?, which slides upon verticalways or guide-rails d2, and the frame is reciprocated to canse the ierto lay the yarn up and down the bobbin, as follows: a

Projecting down from the frame are two toe-pieces, e2, to which areattached the lower ends of two straps,

fl, whose upper ends are fastened to the tops of two `pletes the lasthalf of its rotation, theroll swings in,

by gravity, (or the action of a suitable spring or springs upon the bar12,) allowing the bobbin-frame to fall, the alternate rise and fall ofthe bobbin-framc causing the yarn to be evenly wound upon the bohbin,along a `length of the same,rcorresponding 4to the extent of verticalmovement of the bobbin-frame, and the extelit of this reciprocatingvertical movement may be varied or adjusted by varying the point cfconnection of the link 7a2 to the arm f2,by means of a slct, qaud nutand screw1 lrz.' p v In filling the bobbin, it is necessary to begin tofill at the head, and to work from the head to but a short distancetherefrom, (such distance slowly increasing, however, at eachsuccessive-downward movement of the bobbin,) until the head is lled, andthen to gradually work upward until the whole bobbin is evenly iillcd,and forthis purpose a mechanism is necessary for effecting the gradual,permanent fall of the bob- .bin-frame, so that at each successivedownward movement, the bobbins shall descend slightly further than inthe previous descent of the'bobbin-frame. i

The first or short varying reci procations are effected as follows: g

The swing-bat P passes lloosely through the connecter k2, so that theslotted end of the ,connecter can slide freely in a vertical direction.J oint'ed to the end -of the connecter, is a pendent gear-rachis, withthe teeth of whicha gear-pinion, t", engages, this .pinion being ontheinner end of a short shaft, journalled in a bearing projecting `fromthefoot of the bar Il. At the outer end of this shaft is a ratchet-wheel,a, with the teeth of which a drag-pawL or hook, ci, engages, this pawlbeing pivoted on a pin, '102, projecting from the main frame. As' thebar Z is moved out by the cam o1, the ratchet swinging out with it willbe turned by the hook Vor pawl c, thereby effecting a rotative movementof the pinionn t2, and a descent of the rack e?, such descentlettingdown the link k2, bringing the point of its connection with the bar l"further from the centi-e of movement of' the bar, andl thereby increasiing the extent ofthrow" or rocking movement of the arm 'i2 andarch-heads, and the extent of' vertical movement `of thebobbin-frame.When the slotted end of the link is near the rod mthe extent of verticalmovement of the bobbin-frame is very slight, and.4 thismovementincreases as the connecter is let down at each outward movement of theswing-bar, thereby layiugthe yarn 4over a greater spaceI as thewindingprogresses. But as this increase of movement of the bobbin-frame wouldcarry itfnpA furtheiias well`as down further, thanbefore, the swing-baris set at an inclinav'tion, (in normal position,) so that as` the`connecter "moves down, it also moves back, andthus keeps the bobbin-amedown, or fromf'ascending too high,l that is to say, to su'ch height aswould cause the yarn to wind `overthe head, the increase of movementbeing wholly inthe downward movement of'the bobbins.

,lhe extent of increase of movement of the bobbin- As the` roll isthrown outward bythe cam, the a frame may be varied by setting thedrag-pawl or hook more or less out upon its pivot-pin w'i, by means ofa` The rack s continues thus to regulate the varying movement of thebobbin-frame, until the head 'and lower part of the bobbins have becomefilled, and then a mechanism is brought into operation that causes the ti bobbin-frame to gradnallyfall, (at each reeiprocation,)

until the bobbin is filled, the frame rising less high at i each upwardmovement, and descending lower at each downward movement, this mechanismbeing automatically brought into operation, and that just describedautomatically thrown out of operation, when the bobbin is filled at thehead. This vmechanism .is as follows: l

The rocker-shaft h2, which carries the arch-heads, carries, near oneend, a worm-wheel or sector, aP,iuto the teeth of which engages a worm,b3, ony a shaft, c, turning in suitable bearings in projections from therocker-arm t2. At the top of this shaft is a bevelgear, d3, meshing intoand driven by bevel-pinion @on a shaft, f, at whose outer end is aratchet-wheel, g, actuated by an impelling-pawl, h3, which operates(negatively) to turn the ratchet when the top of the arm t2 moves backor inwardly, that is to say, when the bobbiu-frame is rising, the 'pawlturning on a pin which projects from thewframe u. The point of the pawlit is kept in engagement with the ratchet by having its opposite endweighted.

Each time'the bobbin-frame rises, and the moverise, is effected, theratchet-wheel is rotativcly moved by the pawl, and movement is therebyimparted to the shaft dand its worm, and by the worm to the worm-sectora, thus effecting a change in the position of the arch-head shaft,causing the arch-heads to turn and to lower the-bobhin-frameso thatateach descent such frame will drop lower than at its previous descent,this successive dropping ofthe frame continuing until the bobbins arefilled, causing the yarn to lay in uniform conical strata froth head topoint.`

The change from one' mechanism for thus` regulating the movement ofthebobbin-fiame, to the other, may be antomaticallyeifected through themechanism of the weighted pawl h, and mechanism connecting it with thepaivl 13 as follows: Over the pawljv2 is a weight `or weighted block,t3, hung to the frame `by afpin, It, and having a tailpiec'e projectingfrom it, ass'een at` Z3, the end of which is infthe path of downwardmovement of a pin, p",

` (projecting from the link 152,) when .the pawl 'v2 is in .connectionwith its ratchet. The Apawl c also has a tail-piece, under which onearm, mi, of a {ripper-lever p extends, the other arm, nB of this lever,enteringa notch, "0, inthe weighted end4 of the pawlh, as seen in fig.l. The weight of the pawl holds its notch against the arm a, and keepsthe point of the pawl 71.3 out of connection withits ratchet, asfseen infig. 1. The parts being in position, as seen in such figure, the pin pwill strike the tail-piece l, (when, inthe descent of thelink k2, thehead of the bobbin has become illed,) and will carry down thetail-piece, until the' preponderance of p weight passes over the pin k,

i when the weight ,will swing down, fcausi'ng apin, q,

(projecting from'the tail-piece) to strike the'tail-piece of the` pawlc, throwing Litdown against vthe arm m, causing such armto'lift the'opposite armafthereby liberating the' pawl h, the weightedend b i` whichpresses' thev pawl-point up into engagement with its ratchet, the .pin qlifting the bthe'rpztwl vzfrom its` ratchet' flli'us oneregulatingmechanismis.thrown out'of -operation and they othcrintooperation, the position of the' mechanism being denoted by the dottedlines in fig. 1.i

Vach ratchet, when inr operation, is kept nfronl back movement by asuitable detaining-pawl.

When the bobbins have been filled, the ypawls are `tut away, as seen. atr, in fig. 3, (which is an end View of partof the machine,) and' whenthe bobbinl frame is let down to its lowest extent, the top rail of theframe may be tipped forward, as seen in dotted lines at fig. 1, theframe hanging on the straps f2, and its lower rail being kept upon thevertical guide-rails.

The improvements thus described are intended particularly forwool-spinning, but it will be obvious that they are, to greater or lessextent, applicable to cott0n and other spinning-mechanism.

What is claimed, is- 1. In combination with a carding-cylinder or maincard, and with draw-rolls, and twistentubes, and main twisting-fliers,the mechanism or devices for intermittently griping the roving betweenthe two sets of draw-rolls, so as to uniformly stretch or draw and spinthe yarn, substantially as described.

2. Also, in combination with the bobbin-fmmc, the mechanism forproducing the rise and descent of the frame, substantially as described.n

3. Also,.in combination with thebobbin-frame, the mechanism for varyingthe movement of the bobbins described. i

4. Also, in combination with the bobbin-frame, the mechanism forgradually' effecting the descent of the bobbin-frame to fill the bobbinsevenly, substantially as described. l
